METAL CAP FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 674,692, dated May 21,1901.

Application led September 22, 1900. Serial No. 30,805. (No model.)

To all whom t may concern:

Be it known that I, HENRY S. BREWINGTON, a citizen of the United States,residing at Baltimore, State of Maryland, have invented certain new anduseful Improvements in Metal Caps for Bottles, of which the following isa specification.

My invention is an improvement in means for closing and sealing bottles;and its object is to provide a metallic sealing-cap provided in itsprimary condition with an annular fiat iiange which after the cap hasbeen placed in position on the bottle-mouth is crimped or gathered, sothat the said crimps or gathers will engage the top rim of thebottle-mouth.

I am aware that it is not new to seal the mouths of bottles by metalliccaps whose sides are primarily stamped into a corrugated form before thecaps are applied to the bottlemouth. The said caps after their sideshave been corrugated are applied to the bottlemouth, and the corrugatedsides are then bent in under an annular shoulder at the rim of thebottle-mouth. This cap and its mode of application to the bottle areradically different from my invention.

My invention comprehends sealing the bottlc-mouth by a metallic capwhich in primary condition has a crown and an annular out`wardly-eXtending flat flange similar in form to a sailor-hat. The cap inthis condition is applied to the mouth of the bottle, and then asuitable tool, preferably in the form of a ring, is pressed down aroundthe crown portion of the cap and upon the 'outwardlyextending annulardat ange, which action forces the metal of the fiat flange downwardlyand crimps or gathers said metal so that the said crim ps and gathers,which consist of the excess material resulting from the depression ofthe said annular ange, will engage the top rim of the bottle-mouth, andthus securely seal the said mouth.

Reference is to be had to the accompanying drawings, in which- Figurelis a sectional view of my improved metallic sealing-cap with its flangein the primary condition. Fig. 2 is a side elevation of the upperportion of a bottle embodying my invention and with my improvedsealing-cap in section in its primary condition. Fig. 3 is a diametricalsectional View and also a plan view of the ring-tool for crimping andgathering the cap-iiange while over the bottlemouth. Fig. 4 isa planview of the metallic sealingcap after its fiat flange has been crimpedor gathered into engagement with the top rim of the bottle-mouth. Fig. 5is a side elevation of the upper portion of a bottle with the metallicsealing-cap secured on its mouth. Fig. 6 is a sectional view of the capon another form of bottle-mouth.

My improved sealing-cap A in its primary condition is provided with acrown portion d, in which is set aIparafIin-coatedcmlgllipl: mlQLand anannular flat flange c extends outwardly from the edge of the crownportion a, as shown in Figs. l and 2.

The metallic sealing-cap A in its primary condition is applied to themouth of the bottle. A tool, preferably in the form of a ring C, is thenplaced around the crown portion a of said cap and is forced down uponthe annular flat ange c, which action tightly crimps or gathers theexcess metal resulting from the downward depression of said iange aroundthe bottle-mouth rim and securely seals the mouth of the bottle. Itshould be especially noted in this connection (see Fig. 5) that all thecrimps or gathers c thus formed around the bottle-mouth rim lie entirelywithin the vertical sides c2 of the metallic sealing-stopper and do notproject outside of the said sides.

Fig. 6 shows a bottle B whose mouth-rim is provided with anannular swellin the form of a bead d, and when the flange of the sealing-cap iscrimped or gathered around said bead the said crimps or gathers willlikely be larger or smaller at one point than at another, and in orderto cause the said crimps or gathers to be regularly spaced if desired,which will improve the appearance of the bottle, the bottle-mouth rim isprovided with a swell in the form of an outward flare c, in which areformed a circumferential row of exterior notches f, which receive thesaid crimps or gathers of the sealing-cap flange.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

]. The combination of a bottle the exterior sides of whose mouth-rim areprovided with a circumferential row of notches; and a me- IOO tallicsealing-cap over said mouth-rim and having gathered or crimped portionswhich take into the said notches and which consist of the excessmaterial resulting from the depression of an annular outwardly-extendingflange with which the cap is primarily pro-` vided, substantially as setforth.

2. The combination ofa bottle whose mouthrim is provided with anexterior swell, and a metallic fiat topped sealingcap over saidmouth-rim and having gathered or crimped portions under said swell andwhich consist of the excess material resulting from the depression in adirect line of an annular outwardly-extending Hat iiange with which the
